To whomtt may concern:

Be it known that I, EDwAnn MILNER, of Mar-.

quette, in the county of v Marquette, and State of Michigan, have invented anew and useful Improvement in a. Compound for Preserving Drain-Tile, Under-ground Tubing, &c.; and I do declare that tlf e following is a true and accurate description there- 0 The nature of this invention relates-to the compo sition of a fluid to be applied to drain-tiles, bricks for sewers, wooden water-pipes, and other articles exposed to decay from dampness.

The invention consists in coating or impregnating suchartic'leswith a compound prepared of the ingredients in or about the proportions hereinafter mentioned.

To make one gallon of the compound, the following ingredients are required:

Grude gutta-percha l oune.

Turpentine pint.

Goal-tar 5 pints.

Common glue i}; pound.

Isinglass 1 ounce.

Pulverized soap-stone .12 ounces.

, Asphaltum. .i. .l-pound.

Plaster of Paris, or Paris whitc 2 pounds.

J apan varnish.. 1 pint.-

Gum-shellac 2; pound Sugar of lead 1111 2 ounces.

Gelatine c 1 ounce.

In compounding large quantities, the alcohol, turpentine, sugar of lead, and gum-shellac are reduced to one half the proportionate amounts above named.

'added,-the varnish last.

to simmer slowly for fifteen minutes, being gently To prepare the compound for use, in a vessel containing sufiicient warm water dissolve the gelatine,

stirred to thoroughly almalgamate the ingredients, when the compound is ready for use, which is preferably by dipping the articles to be preserved therein, and immediately withdrawing them; they soon dry; the compound, if the material be very porous, permeating every part, and in all cases forming a hard enamel-like surface, impervious to water, and not to be afiected by frost. I

Drain-tiles are rendered by this process practically indestructible after being properly laid. vVooden and iron tubing, wooden and metallic tanks, bricks for sewersand foundations, in fact, all materials exposed to decay from moisture, will be eifectually preserved if treated with the above-described compound.

That I claim as my invention, and desire to secure by Letters Patent, isi A preserving compound, when composed of the in gredicnts and in or about the proportions herein de- EDWARD MILNER.
